TI  - [Effect of temperature on methanogenic pathway during household waste anaerobic 
      digestion by stable carbon isotopic signature of CH4].
PG  - 3252-7
AB  - The methanogenic pathway during anaerobic digestion of household waste was 
      investigated by stable carbon isotopic signature analysis, and testified by the 
      analysis of gas production, leachate characteristics and microbial fluorescence 
      in situ hybridization (FISH) methods. Furthemore, the difference of methanogenic 
      pathway between mesophilic and thermophilic anaerobic digestion was also 
      discussed. Results showed that under mesophilic conditions, the isotopic stable 
      carbon signature of CH4 (delta13 CH4) initially decreased to -69.5 per thousand, 
      indicating that CH4 was produced from CO2 and H2 by hydrogenotrophic methanogens. 
      When active CH4 production phase started, the delta13 CH4 values quickly 
      increased to -23.8 per thousand, which indicated more and more CH4 were formed by 
      aceticlastic methanogens, dominantly the family of Methanosarcinaceae, shown by 
      the FISH results. The delta13 CH4 values decreased successively and ultimately 
      remained at -55 per thousand, indicating that the fraction of aceticlastic 
      methanogenesis finally decreased to a steady level comparative with CO2-derived 
      methanogenesis at the steady slow methane production phase. Under thermophilic 
      conditions, the delta13 CH4 values remained at a level about -70 per thousand, 
      showing that methane were solely produced from CO2 reduction, and acetate 
      syntrophic oxidation happened during the active methane production phase.
